Breakthrough Casual is a good mode but it ends too quickly

Title. Breakthrough Casual ends too quickly because its very easy for the defenders to mow down waves of bots.  I suggest making it so Bots don't effect the death counter in the same way.  Maybe make them worth only half (or less) a kill. Or maybe implement a time limit instead of death count.  Idk what would be ideal.

The most fun is had at killing a bunch of bots with a sprinkling of real opponents and teammates. So prolonging those matches would make players happier.
